Sherlock Ohms: Antenna Tower 4 Has No Base Current

Sherlock
Ohms is a regular feature of Design News that presents
submissions from readers about troubleshooting challenges and how they
were solved. This story titled "Antenna
Tower 4 Has No Base Current" relates a broadcast station engineer's
experience in troubleshooting a transmission cable problem between the
radio station and its tower located ¼-mile away. Anyone not familiar
with the type of lines run over those distances might be surprised at
the culprit. Jim Flinn,
friend from my USAF radar tech school days, spent many of his post-USAF
years running his own commercial radio broadcast station maintenance
company. The stories he has told and pictures he has shown me of some
of those installations, which he says is more the rule than the exception,
make you wonder how anyone stays on the air.
